Pancake caught: to do with physical education (5)
I believe the answer is:
crepe
'pancake' is the definition.
(I know that crepe is a type of pancake)
'caught to do with physical education' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'to do with' becomes 're' (regarding).
'physical education' becomes 'pe'.
'c'+'re'+'pe'='CREPE'
(Other definitions for crepe that I've seen before include "Fabric with a wrinkled surface" , "Crinkled paper or fabric" , "Crinkly fabric and French pancake" , "Crinkly paper" , "Material - French pancake" .)
